使用改造 android 裁剪后图像未上传

Question

我指的是本教程的裁剪 --> https://www.android-examples.com/android-image-cropping-example-tutorial-pick-gallery-camera/

它将裁剪的图像放置在 imageview 中的编辑个人资料活动中提交它显示成功更新成功..但在帐户活动中它没有在个人资料图片上显示图像...

调试时它只显示这个--> data:image/png;base64但不显示编码字符串(AVDBJSV3jq..)

为什么 convertostring 为空，为什么不在此数据后附加字符串：image/png;base64

我不知道为什么它是空的

需要帮助提前致谢

以下是我的代码

您已将位图放入新变量中。 你必须把它放到全局变量中。

bitmap = bundle!!.getParcelable<Bitmap>("data") profile?.setImageBitmap(bitmap)

只是删除val之前bitmap ，你正在试图树立新的位图图像到变量。
